. Elements of zoölogy. Zoology. Fig. 45.—A moss animal (Plumatella repens), zooids expanded and retracted. Fig. 46.—Brachiopod showing arms. Class V.—Lamp Shells (Brachiopodd). The Brachiopods (Fig. 46) are worms that secrete enequivalved shells with or without hinges. The arms are on one side of the mouth, and in some appear in spirals supported by loops. By the motion of the fringes of the arms, food is thrown into the mouth ; they are also re- spiratory organs. The Lingula (Fig. 47) is an example. Fig. 47.—Lingula anatina. common in the sand south of Cape Charles, where they make sand-tubes
